The fusion techniques have become an important aspect of Dragon Ball, especially since their introduction during the Buu Saga of Dragon Ball Z. Fans of the series have shown great affection for these fusion warriors.
Vegito is the result of the fusion between Goku and Vegeta using the Potara earrings. These earrings have the unique ability to merge two individuals into one being, significantly enhancing their combined power. Vegito first appears in Dragon Ball Z, showcasing a personality that is a blend of Goku’s carefree nature and Vegeta’s prideful determination.

However, many fans are curious to know if Vegito is indeed the strongest fusion warrior in the Dragon Ball universe.
According to Elder Kai’s description, the Potara fusion creates a warrior much more powerful than those formed using the Fusion Dance technique. Moreover, fans have noted that using the Potara earrings allows for a merging of powers far superior to the capabilities of the Fusion Dance, which only combines the strength of the two warriors into a single entity.
Throughout the Dragon Ball saga, Potara earrings have been used to fuse a total of five times. The first two instances involved Kibito Kai and Elder Kai, while the third and fourth instances were Vegito, and the fifth instance was Zamasu.
When Goku and Vegeta first used the Potara earrings, they merged into Vegito specifically to combat Buuhan, Super Buu, who had absorbed Mystic Gohan, Gotenks, and Piccolo. Even after absorbing such formidable fighters, Super Buu still lacked the power and speed to stand against Vegito in battle.
In Dragon Ball Super, the Potara earrings were also used by Zamasu to merge with Black Goku in the Future Trunks saga. To face a powerful fusion warrior, Goku and Vegeta again decided to fuse into Vegito. This time, they achieved the Super Saiyan God form, significantly amplifying Vegito’s power.

In the battle between Vegito Blue and Zamasu, it becomes clear that the fusion warrior created from Goku and Vegeta exerts a tremendous amount of pressure. Therefore, Vegito Blue can also be considered one of the most powerful fusion warriors ever depicted in the Dragon Ball series up to this point.
